A powerful Wi-Fi antenna-gun

This is a downtime in manufacturing and very powerful as a gun Wi-Fi antenna. With it, you can receive and transmit a Wi-Fi signal not only hundreds of meters, but several kilometers! The antenna cannon resembles the look of a space blaster and, just like this fantastic weapon, has a directional and very powerful action.

This is a directional antenna. And this property gives a large reception distance due to the large concentration of the signal in one direction.

Antenna drawing scheme

The drawing shows the dimensions between the elements of the antenna. Its resonant frequency is set to the middle of the 2.4 GHz Wi-Fi frequency.

You will need

A long hairpin with nuts.

Metal sheet, I took a copper one, since it is very easy to cut. In general, you can take tin from tin cans.

Wi-Fi Adapter.But you can already connect to the existing router.

Manufacture of powerful Wi-Fi antenna-gun

Before you start making an antenna, you need to know that any deviation from the given dimensions will greatly impair its characteristics. Therefore, everything must be done as accurately as possible. Take a sheet of metal and roughly mark the centers of the diameters of the circles. Then we drill the center. For accuracy, place before drilling core or pass a thin drill, and then thick. As a result, the hole diameter should be slightly larger than the stud.

Then take the compass and draw rounds on the metal.

Cut a square first.

Then cut a neat circle.

It turned out circles for the antenna.

Took a long hairpin. Cut the excess length of the antenna,given the width of the nut.

Here is the ready kit for assembly.

Assembling the antenna. It's very simple, as a designer in childhood.

To control the size, I recommend using a metal ruler, as it is more accurate.

In the last two disks you need to make holes for connecting the cable.

We will make the connector with the cable from an old antenna from a router or adapter.

Remove the top cover.

We cut off the insulation. The antenna uncoupled itself because it was pressed.

Next, unsolder the metal cap.

And the connector for the connection is ready.

Ludim drives. Copper in this regard is a great thing.Somehow I made such an antenna from the case of an old computer, so there I had to tinker with acid.

Pass the cable through the hole of the last circle and solder the shield winding to the disk.

Now we let the middle core into the hole of the second disk and solder.

The antenna is almost ready. I will install it on the bracket from the camera. There will be such a home option.

Screw the Wi-Fi adapter to the connector output.

You can wind it with tape or tape to the bracket.

I will put the antenna on the window and direct it to the objects,where there can be a signal.

Wow, how many networks have appeared. Although earlier I caught the signal only of my router. There are not many access points in our city.

The result is amazing.

Add-ons

To enhance the effect, I decided to install such a gun on the roof. But for this, I need to solder, instead of the connector, the usual shielded cable that I use for the satellite dish.

Slightly drill a hole and modify the cable plug.

Fixed with tape.

We put on the roof, located on the pole.

The number of networks exceeded all my expectations.

Result

The result was such that you can send a single antenna without special problems contact at a distance of about 10 kilometers! And it's without any amplifiers and special equipment. With such a powerful Wi-Fi cannon - the antenna can send a signal to the garage, to work, to school, to the dacha. All materials are available to everyone, and everything is very simple.

Watch the video

You can find out more detailed assembly instructions by watching the video below. It also shows the broader tests of this powerful Wi-Fi antenna. PS: If you make a street version, then to isolate and rust, the whole antenna will be nice to paint with ordinary paint on metal.
